Alternator & Regulator: Description

The CS144, 140-amp alternator is used in conjunction with a Body Control Module (BCM). CS stands for charging system, and 144 denotes the outside diameter (in millimeters) of the alternator stator laminations.

The alternator and related charging system circuitry has self-diagnostic capacity. A communication process has been incorporated between the BCM and CS144 alternator. When the alternator circuit exceeds programmed limits, the malfunction may be indicated by the BATTERY NO CHARGE message on the telltale warning lamp cluster.

The voltage regulator is enclosed in a solid mold, mounted inside the alternator. A capacitor, mounted in the end frame, protects the rectifier bridge from high voltage, and suppresses radio noise.
